It’s been three weeks since one of the worst IT security vulnerabilities in history was announced, and consumers are still receiving mixed messages about how to protect themselves. We usually encourage users to install software updates as often as possible, but when it comes to Meltdown and Spectre, that advice comes with an asterisk.

With new vulnerabilities discovered every day, it’s important for users to keep their computers up to date. The problem is many find this process tedious and sometimes ignore it altogether. But if you’re a Mac user, we urge you to install the latest patch as soon as possible.

The macOS 10.13.1 High Sierra update “improves the security, stability, and reliability of your Mac and is recommended for all users.” This is a standard message in most operating system updates, but users seldom pay heed. This time, however, Apple’s latest Mac OS includes a security update that’s essential to keeping your devices safe from KRACK.

Why you should update now

Foremost on Apple’s list of macOS updates is the addition of 70 new emojis.

A glaring security mistake has been discovered in Apple’s most recent desktop operating system. It’s not the sort of vulnerability that requires complicated malware or IT knowledge; anyone can learn this exploit in a matter of minutes to steal your password.

macOS High Sierra, Apple’s newest desktop operating system, aims to enhance current features, fix problems, and improve overall user experience. A long list of refinements await iMac and MacBook users, but here are the ones businesses will find most useful.

When smartphones first outsold PCs in 2010, people no longer have to put up with slow and bulky computers to do business. This comes as no surprise why many stashed their aged PCs away. But there are ways to breathe new life into your ancient laptop and computer, so if you haven’t trashed them, it’s time to plug them in.

In yet another sign that Apple computers are no longer being ignored by hackers, a successful piece of Windows-based malware has been rewritten for MacOS. Instead of encrypting data and holding it for ransom, OSX.Dok skips the extortion and simply steals your bank account information.

High Sierra — Mac’s first full OS upgrade since Snow Leopard in 2009 — has finally been released as public beta. But users who expect shiny new features might feel slightly disappointed as the new OS’ most useful updates are actually under the hood.

macOS version of HandBrake, an open-source video transcoding software that converts multimedia files into various formats, was recently infected with a Trojan. According to HandBreak’s announcement, if you downloaded the app between May 2 (14:30 UTC) and May 6 (11:00 UTC), there’s a 50% chance that your system got infected.

No computer is safe from malware, not even Macs. Even though incidences of viruses and malware are rare for Apple computers, they can still occur with disastrous consequences. Based on one security software firm’s report, MacOS malware grew by 744% in 2016, but the number of attacks were still fewer than attacks on Windows computers.
